Petunia plant named &#39;Kakegawa S29&#39;

ABSTRACT

A Petunia cultivar particularly distinguished by its pale lavender pink flower color and creeping, mounding habit.

BACKGROUND OF THE NEW PLANT

[0001] The present invention comprises a new and distinct cultivar of Petunia, botanically known as Petunia hybrida, and hereinafter referred to by the cultivar name ‘Kakegawa S29’. ‘Kakegawa S29’ originated from a hybridization made in 1997 in Kakegawa, Japan. The male parent was a phenotypically fixed F₃ selection from a cross made in 1994 between two breeding lines, 4UK-1 and P-la. The female parent of ‘Kakegawa S29’ was an F₅ selection known as 89S-829-1 a-1 a-1 a-1, originating from a dwarf multiflora breeding gene pool. F₁ seed was obtained from this cross in 1997.

[0002] Two hundred F₁ plants from the 1997 cross were transplanted to a field in Salinas, Calif. during the summer of 1998. Three lines were selected and vegetatively propagated for further evaluation. The three lines were propagated again in 1999, and evaluated for fixed characteristics and ease of propagation. Final selection of one line from the three was made during the summer of 1999. The line was established as ‘Kakegawa S29’, and determined to have its characteristics firmly fixed.

[0003] ‘Kakegawa S29’ has been found to retain its distinctive characteristics after two years and four cycles of vegetative propagation and this novelty is firmly fixed. The variety has demonstrated stability during this time and has no inherent variation or off-types.

DESCRIPTION OF PHOTOGRAPH

[0004] This new Petunia plant is illustrated by the accompanying photograph which shows blooms, and foliage of the plant in full color, the colors shown being as true as can be reasonably obtained by conventional photographic procedures.

[0005]FIG. 1 shows the entire plant approximately six weeks after transplanting a rooted cutting;

[0006]FIG. 2 shows the mature inflorescence.

DESCRIPTION OF THE NEW CULTIVAR

[0007] The following detailed descriptions set forth the distinctive characteristics of ‘Kakegawa S29’. The data which defines these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Three plants from fully rooted 15 cm diameter pots were transplanted to one 50 cm diameter hanging baskets and grown in the same conditions. Data was collected on plants in 50 cm diameter pots eight weeks after rooted cuttings were transplanted. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London (RHS).

[0014] Environmental Conditions for Plant Growth: Plants were propagated from vegetative cuttings, and grown individually in 15 cm diameter plastic pots in a glass greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizer containing 18% nitrogen, 8% phosphorus and 18% potassium was applied in four, daily irrigations. The fifth irrigation was made with non-fertilized water. Pots were top-dressed with a slow release fertilizer containing 18% nitrogen, 8% phosphorus and 18% potassium. The typical average air temperature was 24C.

[0054] Comparison with Known Cultivars: ‘Kakegawa S29’ is a distinct variety of Petunia owing to its pale lavender pink flower color and creeping, mounding habit. ‘Kakegawa S29’ is most similar to the variety ‘Pink Wave’; however, ‘Kakegawa S29’ has smaller flowers and a different flower color. The table below shows the characteristics that best distinguish the new variety from the comparison variety.
